It's so hard to find that document (I usually can find only through the
developer checklist page). You're right, I forgot the following
statement:
"reimplement virtual functions defined in one of the base classes if it
is safe that programs linked with the prior version of the library call
the implementation in the base class rather than the new one. This is
tricky and might be dangerous. Think twice before doing it. "
I don't know if it's dangerous in this case or not, but unfortunately
the current way broke the kdelibs's compilation. Maybe in this case all
variants of the method should be reimplemented, even if you want to
reimplement only one?
